I've had a bunch of people ask me for the AD DR guide that Guido and I wrote. It used to be on the NetPro website, but as part of the Quest-NetPro website integration process, the NetPro whitepapers have been taken down. I've attached the version from the NetPro site here: NetPro_ADDR_Guide.pdf (1.73 mb).

I'm working on an update for Windows Server 2008, and it will be posted on the Quest website, probably mid-January or so. Sorry for the inconvenience.
